Climbs in Snow Creek Area, 1982. Jim Yoder did several new routes in the Leavenworth area. Perhaps the most notable was Hyperspace on Snow Creek Wall. It is a sustained free climb with four of the eight pitches being 5.10. The crux is a 5.10d slot. Also in early September 1982 Doug Klewin and the late David Stutzman made the first ascent of Bong Buttress, a prominent rock tower between Snow Creek and Rat Creek on the north edge of the Enchantment Lakes plateau.
